15-position 3-row header for power distribution
The 641976-1 is a 15-position, 3-row header from the Universal MATE-N-LOK series, designed for board-to-wire power distribution. The 0.250 in (6.35 mm) pitch sets the board footprint and the per-contact current ceiling — at 12 A the temperature rise stays within the polyamide housing limit. Rated 12 A per circuit at 600 VAC, this header handles moderate power loads in general-purpose equipment. The 3-row layout packs 15 circuits into a compact footprint, useful when board space is tight but current density matters.
Tin-plated contacts for cost-sensitive builds
In a high-cycle or corrosive environment, a gold-plated sibling would be the better call. The 0.155 in (3.94 mm) solder post length gives a solid through-hole fillet on standard 1.6 mm PCBs.
Mates with Universal MATE-N-LOK receptacle housings
Confirm the receptacle circuit count and keying match the 15-position, 3-row layout before ordering.
